On Monday Lindsay Lohan Million Dollar Decorators Episode Doesn't Go As Planned was a top story. Here is the recap: (TMZ) Lindsay Lohan nearly torpedoed her episode of "Million Dollar Decorators" on Bravo -- after the network spent roughly $200,000 renovating Lindsay's Beverly Hills mansion -- because TMZ has learned she refused to film the big reveal moment for the show.

Sources close to Lindsay tell us she agreed to film the segment for the show earlier this year -- and in exchange, the people behind MDD spent $200,000 on expensive furniture and other trappings for her house ... which Lindsay's now renting for $8,000 a month.

We're told Lindsay was initially cooperative -- filming a furniture shopping segment back in March and spending several more days shooting in the home before the renovations.

The show then went to work on the house -- filming the entire renovation process -- but when it came time to shoot the big reveal in April, Lindsay stopped returning their calls.

Lindsay's since been living in the house -- and according to sources, the home is now so messy ... it's completely unfilmable.

We're told MDD producers have since decided to use canned post-renovation footage (without Lindsay) as the big reveal moment.

Calls to the network were not returned. The episode's scheduled to air early next year. - more on this story
